I'm going to have refer to a fine film and graphic novel for this one.
V is for Vendetta!
1 : BLOOD FEUD
2 : an often prolonged series of retaliatory, vengeful, or hostile acts or exchange of such acts <waged a personal vendetta against those who opposed his nomination>
I'm a fan of the movie, like I was a fan of the graphic novel before it. V for Vendetta is about a man who was tested and tortured almost to death by his government and then fought back. It's a bloody story, because V takes revenge upon those who killed millions and tried to kill him. It's a dark tale but the best line resonates:
"People should not be afraid of their governments. Governments should be afraid of their people. "
Amen.
